Definition: (Use the science-related definition.)

A concussion is any injury that causes jarring or shaking of the brain inside the skull including fall or blows.

Causes:

car accidents, play accidents, fights, recreational accidents, sports injuries

Effects:.Symptoms range from mild to severe and may include loss of consciousness, nausea, dizziness, memory loss, altered mood, altered sleep, and problems with balance, coordination, and thinking. Symptoms may last for hours, days, weeks, or months depending on the severity of injury.

Dissection is the detailed, part-by-part analysis of a deceased, preserved specimen.

Purpose:

The purpose of dissection is to learn the anatomy (structure) of an organism.

Advantages:.Dissection provides a tactile (hands-on), observational approach to learning the anatomy (structure) of living things.

Disadvantages

Large numbers of animals are used yearly for this instruction.
